V More specifically, 'itr elates' to a stand for mo tor-driven woodworking tools such "as jointersJ although, of course, the'invention is not limited to *supporting anyparticnlar kind or kinds of machines, l and may, :for' e a pi be usedjforf circular gsaws, shapers, drill presses '01- other de-f vicesit desired.

An object of the invent ion is topr ovide a and: or cabinet having a pleasing appearance and ample strength, and 'whichpan be made with a minimum 01 machine work by' "assembling'a number of separate panels preferably mad fyasf castings and formin the sides of theetandi By.

"Referring fii's'tto Flgi 1, there is illustrated V a stand or c'abine't having a front enen, r leftpaheliJand' a rightpanel 3, the Tea? panel 4-"be'ing shown in Figs; and 3.

oth -qeieets incident to the basting operation .4 59: i i Y on; the edges 'ofthe panels as shown' atl and 8 direction. ;;These comprise atthe joints between the panels, as far as appearance goes. Y

The various panels are held to their neighbors "by means of corner braces or brackets 9, best shown-in Figs. 4, 5, and 6. Each such brace consists of a substantially flat piece of metal, pref erably sheet metal, having an, upstanding flange 1 I0 at two of its edges, said flange being bent substantially at right angles to the flat horizone tal portion of the brace. These braces may also have curved flanges at their rounded edges"; a

show at 53.

' These braces are thin enough and soft enough "'5 tohaveacertain degree of yield, which will permit them to conform to the inner faces of the paneis connected thereby, so that upon securing the" braces in place by tightening the screws or bolts en the casing near its lower end,'and prevents spreading when the rear panel dis removed.

The motor-receiving base I! may be provided with openings of suitable sizes and shapes and proper location to cooperate with most available motors; 3. As shown in Fig, 4 a numberof slots 39 isv provided. Obviously-the ultimate. purchaser of the cabinet may drill other holes in the plate .illin case those initially provided do not accommodate the motonhe plans to mount on the platell. 1

While the motor mounting plate ll stififens athe' casing near its-lower end, in some cases it may be desired to stiffen the upper end of the passing through alined holesinythe flanges will .1

engage closely against the lands 54 and 55 011 the inner faces of the panels, thus producing a very strong andrigid joint which nevertheless has sufiicient yield initially to-permit correction.

for slight irregularities in the castings. Eight such braces are illustrated in the'present stand, four at the top and four at the bottom as will be understood from Figs. 1 andfl. The

securingmeans mployed to fasten the, braces to V the-panels are here; shown as oval head screws ll, having nuts l2 engaged thereon, with lock washers l3 interposed-as shown clearly in Fig. 5.

A slightly different securing means is em-,

ployed to hold the rear panel 4 to the flanges ID of the cooperating braces; Thisconsists of a screw l4 supported'by the flange 10 in any preferred ,way, as by riveting or welding, if riveted having its head inside the said flange, the panel 4 having near each corner an opening I5 toreceive the corresponding screw, which extends outwardly, a manually-operable knurled nut It.

being engaged onthethreads of the screw. In

casing also. For instance, when the removable "panel 4-istaken off, there may be suificient strain in the casing to causethe end panels 2 and 3 'to spring together 'orapart to a small degree, thus makingiit difiicult to replace the panel 4. This defect may be remedied, where it exists, by providing a bar or rod5ii extending across therear of the casingas shown in Figs. 1 and 7, and se--= cured to the end panels 2 and 3 in any preferred way. As shown, it is indicated as riveted. or

welded to two of the upper braces 9.

h' lother pair of the .upper braces! likewise serves a doublepurpose, in that in addition. to

holding-together the panels,.they alsoser v e to support theupper end of the shavings chute 25.

This construction 'is shown at the upper right hand corner of Fig. v1, .where it is seen that the chute 25, h'as a horizontal, Iiar 1ge26 at its upper,

end, resting on the right hand braces 9,, andsecured thereto in any desired way, for example, by.

. screwsjT-or the like ,passing through the flange- 26 and threadedintothebraces,9. The panel 2: has an opening 28 formed therein, with an in-. wardly extending flange 29, which receives the I outer end of the shavings chute 2 5 and supports this way the rear panel 4 may be removed and replaced readily without requiring'the use of; any

tools, which adds to the convenience of thej stand and provides ready access tothe interior of the casing. V w

In-addition; to holding together the. panels which form the casing, the lower braces 9 .a1s0

vided'for adjusting the plate Him a vertical screwsor bolts 19 mounted for example-by riveting. them into holes in the lower braces 9, 'orby welding if preferred each screw; having its head end engaged with th corresponding preferably four" serve to'support a motor-mounting plate ll.

This is shown in Figs, 1, 5, and 6, and serves to support the Inachine-operatingmotor l8, shown,

in dotted lines in Figs. '1 and 2. 'Means are pro-' bracefand its threaded portion :20; extending downwardly, and passing loosely, through a cor-. responding hole 2! in a cornerofthe plate 11; .As stated, each screw ill will preferably be mounted rigidly inits brace 9 so that it may not rotatefnor be capable of moving vertically, although this is not essential but merely con-Y venient.,Aknurled-nut22 is engaged. on each screw l9 below. the plate J7, andamachine nut 2 3 is engaged therewith above saidplate, a lock washer 24 being interposed between each nut the adjacent surface of the plate I Inthis way the vertical position of the plate Il may be adjusted by operating said nuts, .and thereupon the plate may be securely maintained in its final adjusted position bytighteningthe nuts. The} plate I! then serves'also to stiffen and st g h the same as best shown in Fig.1. It will be understood of course, that this chute is open at bothgends so that it may receive the shavings produced atthe top of .the stand and discharge them at the left hand side of Fig. 1.

a The panel I; herein referred to asthesfr panel, may bej'provided with any arbitrary ornamentation, as-shown for example, at 28 and 30. if desired. Removal of v the'rear panel4jgives. access'to the interior of the casing/and .it will. be understood that the pulleyof the motor is at the rear of thecasing, iwhen in the position shown in Fig. 1. It is also very. convenient to placethemotor so that its commutator end and; inspection cover are: at this same end, forease o f;access;.

A'belt guard 3| may. beformed integralwith' the rear panel 4, to accommodate themotor pul.-. ley and the beltorbelts passing over the same;

Thisbelt guard 3| willpreferably alsobe given an ornamental appareance, in keeping withth'e design of the entire cabinet, -for' example as illustrated-in Fig.3. An extension 32"wi1l be pro-' vided'to fit on 'the top of thebelt guard 3|, and

may be secured by providingan inwardly offset lug or flange 33011 the extension 3 2,to fit within the belt guard 3 I, these parts then being secured ont 2,325,083,, tlmeaninherently rigid double-flanged panel is provided.

:At' the upper end corresponding to the base of the machine inof each panel. jthe same ;is 7 preferably curved inwardly asshown' linFiguBiI This serves the'triple purpose, of 'stifiening the; panel, providing, a pleasing appearance, and re-g. ducing the size of thetop of the casing to that:

notches instead of ho1es,-it is possible tocheapen 7 the'manufacture, since such'notches maybe-pro 1 duced by casting and do'not require any coring;

120: the'.notches will be varied to'correspondto the machine with which the casing is to be use'dga'n d drilling or i the like. Obviously-the locations of it will beundrstood that the arrangement shown in Fig. 3 is merely illustrative of one particular instance' 7;. W

At the lower end of each panel there is an out wardly curved portion, which will produce' a somewhatenlarged base when the panels are as: sembled 'to form the cabinet. These portions may have configurations consistent with the 're' mainder 0f the casing, for example}asfillustratedthere maybe an upper curvedjportion'fl; with a lower portion 44 oflset still furtheroutward,- and terminating at thebottom'in'a' slight projection'i'or fiange'45, alla's shown clearly in. Figs 4 V 1 and-2. It will be noted that these-portions are continued correspondingly throughout all {the panels,the panels 2"- and 3' 'each l'iaving 'a substantially straight "central portion, 'withquadjrantal end portions,-as indicated in Figs. Band '4 while-the other two panels have substantially" straight sections of these' projections; or fmold f ing-at the bottom. 1

The panels'fi and 3 also provide means for securing the cabinet to a floor or foundation.

These means-consist of flanges castin the lower: s most portions of said panels, as shown at 46 in the panel 3, such flanges egtendingparallel.td j the floor and having suitable-notches formed 3 therein preferably bycasting, as shown for ex ample at 41, in the-panel 3; The panel 2 prere j ably has a similar flange 48, with two notches 49, onenear each end thereof, as shown'gi'n dotted.
